SOUND-PRODUCING- DEVIGE 7 Application filed October 2, 1929. Serial No.396,750.

This invention relates to sound producing devices, and relates moreparticularly to the class of sound producing devices used in toys anddesigned and adapted to be operated by the action of air.

The invention resides in the structural and functional improvementshereinafter fully described and illustrated in the accompanying drawing,in which Figure 1 is a side view of a toy with one form of the deviceincorporated therein.

Fig. 2 is a section taken on the line 2-2 of Fig. 1.

Fig. 3 is an enlarged section through the device and showing portions ofthe bellows.

Fig. 4 is a view of the device looking in the direction indicated by theline 44 of Fig. 3.

Fig. 5 is a section taken on the line 5-5 of Fig. 4.

Fig. 6 is a plan view of a modified form of device.

Fig. 7 is a section taken on the line 77 of Fig. 6.

Referring now more particularly to Figs. 1 to 5 inclusive of thedrawing, it will be apparent that there is shown a bellows type of toycommonly known as a squeezum toy consisting of a bellows 10 and a soundproducing device 11 arranged within the bellows so and designed andadapted to be operated by air expelled from the bellows by squeezing thesame. The bellows 10 in the present instance consists of two flexibleplates or cardboard 12 which are glued together along their marginaledges to form an airtight chamber 13. The cardboard members 12 are actedupon by a spring means not shown which yieldably maintains them in thechamber forming relationship. The construction and arrangement is suchthat when the members 12 are brought together the air within the chamber13 will be expelled therefrom for the purpose of operating the device11.

The sound producing device 11 includes a sound box 14 consisting of abase member 15 and a hollow member 16, both members being made of metal,and both being of circular shape. The base member 15 is crimped topresent spaced ribs 17 between which a reed un1t 50 is arranged. Thehollow member 16 1s secured to the base member 15 in any suitable mannerand in the present instance the marginal edge of the base memberis'turned inwardly over the marginal edge of the hollow member 16 as at18. The reed unit consists of a metal reed 19 and a tubi-form member 20,the reed being operatively secured in place on the member 20 in anysuitable manner. Thereed unit projects from the box 14," and; the freeendof the reed which vibrates being outermost as shown most clearly inFigs. 3 and 4. The inner end of the member 20 is open to the interior ofthe box 14. The base member 15 has formed integral therewith a tubularmember 21 which serves as a means for attaching the device 11 to one ofthe cardboard members 12, and also for forming an airpassage 22 for thedevice 11. The-tubular member 21 is projected through a hole in therelated cardboard member 12 and is crushed down as at 23 to securelyfasten the device 11 in place. It will nowbe understood that when V themembers 12 of the bellows 10 are pressed toward each other, air whichhas entered the chamber 13 will be expelled, and in so being expelledwill cause the reed 19 to vibrate thereby producing the sound; the airescaping from the box through the passage 22. In the form" of theinvention hereinabove described, the invention resides in the manner ofsecuring the reed unit in place by the structuralfeatures of themetalmembers l5 and 16 of the box 14, and in the manner of attaching thedevice 11 by the provision of the tubular member 21, which as stated,constitutes an 85. attaching means and also forms an air passage.

In Figs. 6 and 7 there is shown a modified form of sound producingdevice, which differs from the device 11 hereinbefore described, in thatit includes a sound box 24 which is designed and adapted to change thesound pitch of the device. Accordingly, the box 24 consists of a basemember 25 and hollow members 26 and 27. The reed unit 28 is V secured inplace in the base member 25 in the manner set forth above. The hollowmember 26 is fixedly secured to the base member 25, while the hollowmember 27 is slidably connected with the base member 25 so as to beadjustable relatively to the hollow member 26, to vary the size of theair chamber of the box 24, for the purpose of changing the sound pitchof the device. It is to be 5 understood that before this type of soundproducing device is incorporated in a toy, the hollow member 27 will beset in such proper relation with respect to the hollow -member 26 toproduce the desired sound. I claim:

1. A sound producing device having a box which forms an air chamberthrough which air circulates for the purpose of producing the sound,said box comprising a base member, a hollow member fixed to said basemem ber, a second hollow member connected with said base member forfixed adjustment in relation to said fixed hollow member, to vary thesize of said chamber, for the purpose of changing the sound pitch of thedevice, and means on the base member for securing the device in place. p

2. A sound producing device comprising the combination of a reed unit,and a hollow 5 body on which said reed unit is positioned,

said body having an integral tubular member which serves for the purposeof forming an air passage for said body, and also for securing thedevice to an appurtenance adapted to vibrate the reed of said unit, andsaid body consisting of sections adjustable to a fixed relation for thepurpose of changing the sound pitch of the device.

3. A sound producing device comprising the combination of a reed unit,and a hollow body having spaced integral ribs, said unit beingpositioned between and secured to said ribs, and said body having anintegral tubular member, which serves for the purpose of forming an airpassage for said body, and

also for securing the device to an appurtenance adapted to vibrate thereed of said unit.
